takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.

2) There are three ways of resetting the HOLD mode.
(1) Setting the reset pin to the lower level
(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
(3) Having an interrupt source established at port 0
•
X'tal HOLD mode : Suspends instruction execution and the operation of the peripheral circuits except the
base timer.
1) The CF and RC oscillators automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are four ways of resetting the X'tal HOLD mode.
